GARBAGE INGINERATOB.

Application filed January 18, 1925. Serial No. 2,165.

To all whom it may com-em.-

Be it known that I, MATHIAS ANToNf- KoHN, a gitizen of the United States, and resident or Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Garbage Incinerators; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to garbage incinerators, and is particularly directed to an incinerator in w ich a gas or other type of burner is mounted below the charge, and in general this invention is an im rovement over that disclosed in my prior atent No. 1,468, i50 of September 18, 1923, for garbage incinerator, and has the same general objects as such invention. T In arbage incinerators employing a flame distri utor, difiiculty has been experienced in maintaining the correct position of the distributor. In my previous patent I sup:

ported the lower end of the distributor on,

the grate. However, this invention is dew ich a flame distributor is supported independently of the grate, and in which freedom of motion of the grate is attained without disturbing the flame distributor.

Further objects are to provide a garbage incinerator in which a distributor is provided, and in which a movable grate and a movable burner are both employed and are adapted for simultaneous o eration by means of a single instrumentallty such as a manipulating lever, and which is adapted to dump the residue after burning, in a simple and easy manner.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a vertical sectional view through the incinerator, such view corres onding to a section on the line 11 of Fi ure'2 is a horizon'tal sectional view on the line 2-2 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 1, the flame distributor being removed.

signed to provide a garbage incinerator in spaced relation to t e outer shell 1 by means of the flanges 8 of the lugs. The colander 4 1s provi ed with an inwardly projecting rib or flange 5 upon which the conical hopper 6 rests. This hopper extends downwardly and is provided with a rectangular lower open portion 7 through which the grate shaft and the burner shaft and supply pipe project, as will be described hereinafter.

The grate consists of a relatively small stationary portion 8, as may be seen from Figure 2, which is equipped with tapered end lugs 9 most clearly shown in Figure 3, which seat within clearlysimilar slots in the inner face of the rectangular portion 7. Thus the small stationary portion of the grate is easily removable.

The main body of the grate is indicated at 10' and such portion is pivotally carried upon a relatively short trunnion 11 socketed in one side of the member 7 and a relatively longer trunnion or shaft 12 which'projects through the other side of the member 7, as shown in Figure 2.

- The burner is indicated at 13 and is mounted below the grate. It is supplied by means of the mixing or sup 1y plpe 14 in a manner similar to that disclosed in my above noted patent. This pipe is freely rotatable and permits rocking of the burner. It is accommodated in the portion 7 by means of a slot 15 formed in said'portion, said slot being clearly shown in Flgure 3. A manipulating shaft 16 projects from the other side of the burner in alignment with the pipe 14. This shaft also extends through a slot 17 formed in the rectangular portion 7 of the hopper, as shown in Flgure 4, and 1s preferably provided with a collar 18 (Figure 3) positioned on the inside of the member 7 and with a sleeve or spacer 19 (see Figure 2) positioned on the outer side of the rectangular portion 7, whereby the burner is correctly retained in position within the member 7. The shaft 16 projects through a suitable bearing 20 (see Figure 2) carried by the shell 1, and the burner pipe 14 is similarly carried in a. bearing 21. The shafts 16 and 12 are connected by means of segmental gears 22 and 23 to cause simultaneous rocking of such shafts. This rocking is secured by means of a manipulat ng hand lever 24 (see Figures 1 and 5) whlch is pivotally carried by a hub 25 rigidly secured to a square projecting portlon of a shaft 16.. The hub 25 is provided with a socket portion 26 to limit the outward swing of the manipulating lever 24. A stop 27 (see Figures 2' and 5) is provided to unit the downward rocking of the lever. A second retaining stop 28 is ositioned, as shown in Figure 5, and equipped with a hook 29 behind which the lever 24 may be positioned to retain it in normal position.

Thus when it is desired to discharge the residue after the burning operation, the lever 24 is detached from the retaining hook 29 of the bracket 28 and is rocked in a clockwise direction (see Figure 5)., This rocks the shaft 16, and through the medium of the gears 22 and 23 rocks the shaft 12. The rocking of the shafts 16 and 12 carry the burner 13 and the movable grate 10 into their vertical dotted line positions, shown in Figure 3, and thus permit the ready d1scharge of the residue. To reposition the device, after discharging the residue, it is merely necessary to rock the lever 24 back into its initial vertical position.

In order to insure complete burning of the garbage, a flame distributor 30 is provided and is preferably composed of two substantially similar portions bolted together and provided with discharge apertures 31 along its extent. This flame distributor is provided with a relatively large bell shaped lower portion 32 which receives a large portion of the flame from the burner:-

and distributes the flame and heated products of combustion outwardly through the openings 31 into the central portion of the c arge of garbage.

It is to be particularly noted that this flame distributor is not seated upon the grate but is suspended wholly from the upper portion 33 of the incinerator. A bracket 34 is secured to the under side of the usual portion and is provided with :1. lug 35 rectangular in cross section, as shown in Figure 6.

is provided with a rectangular eyelet portion 37 equipped with a rectangular aperture 38 therein. This rectangular aperture receives the rectangular lug 35 and accurately fits such lug, thus preventing swinging in one direction. Further, the vertical faces of the projection'36 of the lug and the bracket '34 receiire the correspondingly contoured eyelet portion 37 therebetween, as shown clearly in Figure 1, and prevent swinging motion in the other direction. Thus the flame distributor is securely retained in vertical correct position in a simple and effective manner and is readily removable as occasion may demand. The incinerator is, of course, provided with a flue 39 and a receiving chute 38 in the usual manner.

The incinerator may conveniently be provided with a base 40 and with a discharge door 41 in a manner similar to that disclosed in my above noted patent.

It will thus be seen that a garbage incinerator has been provided in which a flame distributor is suspended in a fixed position from the upper portion of the incinerator and is free from attachment to the grate.

It will further be seen that an incinerator is provided which has a freely movable grate and a freely movable burner and that means are furnished for causing simultaneous operation of the grate and of the burner to permit ready discharge of the residue after completion of the burning operation.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

I claim:

1. A garbage incinerator comprising an outer shell having a transverse top, a perforated colander positioned therein and spaced therefrom, and having a downwardly extending open hopper, a grate carried in the lower portion of said hopper, a burner positioned below said grate and operatively connected to said grate, means for simultaneously rocking said grate and burner, a hollow vertical flame distributor positioned above said grate and having an open bottom and outwardly opening apertures, and means carried by said transverse top and cooperating with the upper ortion of said flame distributor to hold said flame distributor against rockin motion.

2. A garbage inclnerator comprising an outer shell having a transverse top, a perforate colander positioned therein and spaced herefrom and having a downwardly extending hopper, a pivoted grate carried in the lower portion of said hopper, a pivoted burner independent of said grate and mounted below said grate, a hollow flame distributor mounted above said grate and having an open bottom and outwardly opening apertures, gearing connectin the burner and the grate, and means or simultaneously rocking said burner and grate about their 10 independent pivots.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

MATHIAS ANTON KOHN.
